Every once in a while, Christians worried about the declining state of society step out into the streets and call for revival.

Sunday afternoon was such a time in downtown Charleston.

About 100 Christians of all stripes gathered in Washington Square for prayer and worship. Organizers said it was to show the need for religion in the public square “at this precarious and confusing time in our national life.”

The park is across the Four Corners of the Law, a landmark that includes the oldest church in downtown Charleston and three government buildings.

The pastor of that church, the Rev. Al Zadig of St. Michael’s Church, took the lead Sunday.

“There is a stability in the local church for the local community,” he said. “There are times when we’ve got to get out of the four walls into the community.”

Zadig read letters of support from Charleston Mayor Joe Riley and U.S. Sen. Lindsey Graham, a South Carolina Republican. State Rep. Samuel Rivers Jr., a Goose Creek Republican who is also a pastor, called on Christians to insist on godly leadership.

The Rev. Marshall Blalock, pastor of First Baptist Church of Charleston, also spoke and prayed about the need for godly leaders.

First Scots Presbyterian Church was also a local sponsor.

The rally was part of a national effort called Citywide Prayer for Christ, which is coordinated by Global Leadership Dynamics. The ministry is led by the pastor of Billy Graham’s home church, the Rev. Christian Zebley of Evangelical Presbyterian Church in Montreat, N.C.

“You are the Holy City, and we are praying for a movement of holiness that starts here,” Zebley said Sunday in Charleston. “God is doing something here today that I believe will be noticed around the world … Christians uniting in the public square.”

A representative of the Billy Graham Evangelistic Association also spoke. So did Gerald Long, the executive director of Alpha USA, a program to make evangelical Christianity more accessible to those outside the church.
